VNC 4 is not running as root
Solution -Go to that folder in where your team viewer is installed.
In my case it is opt
Teamviewer > teamviewer > 6 > bin > wrapper
open this wrapper in editor
and makes this line as hidden
# if [ $userid = 0 ] ; then
# die "TeamViewer must not be executed as root!"
# fi
The reason behind that $userid == 0 means it is as root so disable this one.
Now run you teamviewer as root. It works
If you have any query then write it to me

Some php questions with Answer
1. How can we submit a form without a submit button?
Ans - The main idea behind this is to use Java script submit() function in order to submit the form without explicitly clicking any submit button. You can attach the document.formname.submit() method to onclick, onchange events of different inputs and perform the form submission. you
can even built a timer function where you can automatically submit the form after xx seconds once the loading is done (can be seen in online test sites).
2. How can we create a database using PHP and MySQL?
Ans - We can create MySQL database with the use of
mysql_create_db('Database Name')
3. What are the different tables present in MySQL, which type of table is generated when we are creating a table
Ans - Total 5 types of tables present in MySql
1. MyISAM
2. Heap
3. Merge
4. INNO DB
5. ISAM
When we are creating any table with syntax
create table employee (eno int(2),ename varchar(10))
By default MyISAM is generated
4. How To Get the Uploaded File Information in the Receiving Script?
Ans - Once the Web server received the uploaded file, it will call the PHP script specified in the form action attribute to process them. This receiving PHP script can get the uploaded file information through the predefined array called $_FILES. Uploaded file information is organized in $_FILES as a two-dimensional array as:
$_FILES[$fieldName]['name'] – The Original file name on the browser system.
$_FILES[$fieldName]['type'] – The file type determined by the browser.
$_FILES[$fieldName]['size'] – The Number of bytes of the file content.
$_FILES[$fieldName]['tmp_name'] – The temporary filename of the file in which the uploaded file was stored on the server.
$_FILES[$fieldName]['error'] – The error code associated with this file upload.
5. WHAT ARE THE DIFFERENT TYPES OF ERRORS IN PHP?
Ans - Three basic types of runtime errors in PHP:
1. Notices: These are trivial, non-critical errors that PHP encounters while executing a script – for example, accessing a variable that has not yet been defined. By default, such errors are not displayed to the user at all – although you can change this default behavior.
2. Warnings: These are more serious errors – for example, attempting to include() a file which does not exist. By default, these errors are displayed to the user, but they do not result in script termination.
3. Fatal errors: These are critical errors – for example, instantiating an object of a non-existent class, or calling a non-existent function. These errors cause the immediate termination of the script, and PHP’s default behavior is to display them to the user when they take place.
Internally, these variations are represented by twelve different error types
